Another interesting pregnancy fact

I read in some weighty tome that if you suffer an injury during pregnancy you might as well just get used to it as your body's priority is going to be on growing the baby rather than on healing itself.
My skin gets very dry and itchy during winter. Five days ago I was scratching my leg when the skin just split apart like tissue paper. The cut isn't deep but it is surprisingly long. Not only has it not even started to heal yet but I think it's begun to travel further down my leg - spreading like a crack in a windshield.
Surely this isn't fair. ("Welcome to motherhood," I hear my mum-friends say.) Seriously though, I'm growing an entire human being at the moment, albeit on a miniature scale, so why can't I grow my own skin back? I don't want to sound childish but I was in this body first!
Spidermonkey said he thought pregnant women would have super powers of rejuvenation and I have to say I agree with him. What happened to 'glowing'? At the moment any area below my knees looks leprous. Well, it's not like I was planning on strutting around in a mini skirt any time soon anyway. And may I add "hmph".
